Move fit parameters to class __init__

[jnothman]

In the scikit-learn API, the only arguments to fit should be arrays aligned with the data samples. Other parameters should be supplied through the class constructor. This allows the parameters to be grid-searched. It will also make your API more compatible with misvm which would be useful.

Hi @jnothman. I just read your comment. Thanks for the feedback. I have this project a little abandoned. Hope to continue with it sometime in the future and implement your suggestions. Cheers,
